[erlang-questions] Trouble compiling erlang on OS X intel

Darwin Ports has changed it's name to Mac Ports (http://www.macports.org/). I installed R11B-4 with 
Mac Ports without any problem. I'm just not up to date... R11B-5 is available.

Also, there is an smp variant available for the Mac Ports erlang package... I think you would do:

port install erlang +smp

Or something like that.
